To all whom t may concern:

Be it known that I, FREDERICK W. ScHRoE- DER, of London, England, have invented a new and useful Apparatus for Sha ing the Ends of Billiard-Cues, of which the fbllowing is a full, clear, and exact description, reference being had to the accompanying draw` ings, forming part of this specification, in whichf Figure 1 is a longitudinal section of my improved device, showing the tip'and bit in position therein. Fig. 2 is a side elevation of the device, partly broken away. Fig.` 3 is a cross-sectionon the line III III of Fig. l.

My invention relates to the shaping of the ends of billiard-cues to receive the tips; Vand the object of the invention is to provide a simple and cheap apparatus for centering and clamping the tip and forA correctly guiding the bit which squares the end and shapes the receiving-hole.

In the drawings, 2 re resents a steel tube having within it three at springs 3, which are carried on pins 3 at each end, these pins being eened over at one side to prevent their rawing completely within the tube.y These springs are preferably flaring or beveled slightly at the entering in to allow the tip to pass into the space between them. Around that portion of the base-tube 2 containing 'the longitudinal springs are two sleeves 4 and 5. These sleeves are flared or provided with'bell-mouths 6 and 7 at their opposite ends, and upon one of them is screwed a sleeve 8, the o posite end of which abuts against the other s eeve. By screwing upon this sleeve 8 the flared sleeves may be simultaneously forced in o posite directions,

thus compressing inward y upon the beveled` faces of the spring-pins. Beyond the sleeves and springs the base-tube is preferably provided with 'a window 9, through which the end of the cue can be seen.

In using the apparatus7 the sleeves bein loose upon the base-tube, the tip is force into position where its end can be seen through the window. The sleeve 8 is then turned to force the flaring sleeves 4 and 5 apart, thus forcing the pins and springs inwardly and clamping the cue in position.

i The bit 10 (shown in Fig. l) is preferably rovided with a stepped front portion 11 to lorm a stepped hole in the cue, the lip portions 12 squaring the front end of the cue. A portion 13 of this bit is cylindrical and is a neat fit within the base-tube, which guides and directs it. The bit may be used with an ordinary hand-stock.

The advantages of my invention result from the simplicity and efficiency of the apparatus. The cue may be quickly and easily centered and clamped in the guide device which centers the bit. i

Many variations may be made in the form and arrangement of the radial clam ing devices, the tubes, &c., without departing from my invention.

I claim- 1. In a cue-finishingdevice, a tubular supp port having longitudinal inner flat springs with projecting pins at each end, a pair of sleeves arranged to act upon the lpins, Vand means for simultaneously forcin t e sleeves apart, substantially as describe. Y

2. In apparatus of the character described, two sets of radially-movable clamping devices, two oppositely-movable sleeves actuating said devices, and a screw device be` tween the sleeves arranged to force them simultaneously in opposite directions with substantially equal pressure; substantially as described. i

3. An apparatus for finishing billiard-cues `comprising in one structure a tubular toolguide adapted to receive interchangeable tools, and a tubular support in alinement with said guide having internal longitudinal clamping-bars, a pair of external sleeves cooperating with said b ars, and me ans operating to displace the said sleeves lon itudinally relative to each other; substantia ly as described.

4. In apparatus of the character herein described a combined tool-guide and selfcentering cue-grip comprising a cylindrical tube adapted to rece=ve the tool at one end and the end of the cue at the other, a plurality of clamping-bars within the cue 'end of thevsaid tube, holes in the cue end of the tube and pins in the said clamping-bars projecting v through the said holes, said pins having beveled heads, a pair of sleeves surrounding the tube and having flared ends adapted to cooperate with the beveled heads of the clamping-bar pins, and means for moving the said sleeves relatively to each other in an axial di- IOO
